Sweden the pot
What you say to a gal with small boobs who offers to let you "squeeze theeze" in exchange for a favor dat she's asking of you; your meaning is dat you wish her to fetch a more-amply-endowed female like da women in Northern-European regions, so dat you can sample HER "merchandise" instead, better satisfying your softness-thirsting hands and thus making you feel more willing to accommodate da "original" chick's request.
Directing a flat-bosomed gal to "Sweden the pot" in response to her "You may feel me up as reimbursement for your assisting me" proposal may indeed gain you more pleasure immediately and "up-front" (pun not intended, but it certainly works here, since a fuller-chested lady possesses more kneadable deliciousness "up front"), but it will likely make da less-buxom chick feel insulted and inadequate, and therefore less likely to want to continue associating with you in a friendly way --- she will resentfully/disgustedly feel as if all you care about is da volume and firmness of a female's ta-tas, rather than da size of her heart.
